Guidelines that allow sale of tainted infant formula are unsafe, group says

The decision by the Food and Drug Administration to allow U.S.-manufactured infant formula contaminated with melamine or its byproducts onto store shelves is "seriously flawed" and medically risky because parents may feed their babies more than one product, scientists at the nonprofit group Consumers Union said Friday.

Rates of women who are opting for preventive mastectomies, such as Angeline Jolie, have increased by an estimated 50 percent in recent years, experts say. But many doctors are puzzled because the operation doesn't carry a 100 percent guarantee, it's major surgery -- and women have other options, from a once-a-day pill to careful monitoring.

The FDA detected melamine and its byproduct cyanuric acid separately in four of 89 containers of infant formula tested in the fall, but never at the same time. A can of milk-based liquid Nestle Good Start Supreme Infant Formula with Iron contained traces of melamine while three different cans of Mead Johnson's Enfamil LIPIL with Iron had traces of cyanuric acid.

The FDA says studies show potentially dangerous health effects from the industrial chemicals only when both are present. The lack of dual contamination is key, say agency officials, and thus there have been no recalls of the tainted formula.

In a letter Friday, consumer advocates told FDA commissioner Andrew C. von Eschenbach and U.S. Department of Health and Human Services Secretary-Designate Tom Daschle that they were concerned the FDA was assuming parents would never feed their babies more than one type of formula. They said they had heard from a concerned mother who routinely fed her baby two different formulas because "one caused constipation, and one caused loose bowels, but together the baby's digestion seemed just right."

Infants could be exposed to combined chemcials
"FDA should regulate infant formula based on an assumption that infants may be exposed to melamine and cyanuric acid in combination," they wrote.

The U.S. government began testing domestically produced infant formula in September, soon after melamine-spiked formula was blamed in the deaths of babies in China; so far melamine has been implicated in the sickening of nearly 300,000 babies in China and killing at least six infants there.

In China, melamine was intentionally dumped into watered-down milk to trick food quality tests into showing higher protein levels than actually existed. Byproducts of the milk ended up in infant formula, coffee creamers, even biscuits.

The concentrations of melamine there were extraordinarily high, as much as 2,500 parts per million. The concentrations detected in the U.S. infant formula samples were 10,000 times smaller, as low as 0.25 parts per million. The agency released the results only after The Associated Press filed a Freedom of Information Act request.

There has been very little research on what levels are safe. Cats had kidney failure after eating 32 parts per million of cyanuric acid and 32 parts per million of melamine.

The FDA did not respond immediately to requests for comment.
